To all whom it may concern:

Be itknownthat 1, JOHN O. FJARLI, a

citizen of the United States, residing at lierwick, in the county of Mcl-lenry and State of North Dakota, have invented new anduseful.Improvements in Gang-Plows, of which the following is a specification,

This invention relates to certain new and useful improvements in gan plows,-such as end with a pulley l5. Attached to the plow frames are chains 16, the chain of each plow-frame leading upwardly over the pol-- ley of its respective beam 14. It will .be

understood that as concernsthe exact form of the lifting devices immediately associated with the plows there can be considerable are drawn by traction-or 0t er power vehi- (:les, or are operated by self contained bower.

v The object or the invention is .to provide means for raising the plows out ofthe soil and forlowering the same into the soil at will through means operated from the traction wheel of the vehicle, or any other rotary element thereon,

The above and other characteristic features of the invention are fully illustrated in the accompanying drawings forming a part of this specification and wh rein like characters of reference design e corresponding views, in which: i v

Figure 1 is a top plan view. Fig, 2 is a vertical sectional view taken on line 2-2 of parts throughout the several 1. Figs. 3, 4 and 5 are views in side elevation. of the locking disks detached illuswheels thereon for the plow frame raising and lowering chains. Fig. 6 is a top plan view of one of the locking disks with its complement ratchet wheel, and Fig. 7 is a diagram in two parts illustrating the theory of operation of the plow raising devices.

Reference numeral 1 designates the vehicle finale. 2 one of the traction wheels therefor, and 3 the other traction Wheel from which the plow raising and lowering mechanism operated. Tl e vehicle frame essentially comprises parallel front and intermediate bars l and 5 and diagonal rear bar 6, and side bars 7 and 8. I

The plows are mounted in duplicateon plow frames 9, 10, i1 and 12, said frames being suitably connected with the vehicle frame for raising and lowering. The plows and fran'mr-z therefor are arranged in diagonal series parallel with the said rear bar 6 of the vehicle frame.- There are provided suitable devices for lifting the plows from the ground. the vehicle frame and projecting rearwardly therefrom and above each of said plow frames a beam 14 provided in its rear As shown, there is secured to variation within the sco e of the invention.

The chains 16 extend orwardly over and 65 around the mainshaft l7 and then rearwardly and downwardly to the intermediate vehicle frame bar 5 to which the free ends ofsaid chains are attached. The said main shaft 17 has-its free ends journaled in the vehicle side-bars 7 and 8 and extends across "the vehicleirame between and parallel with the said bars fl and 5. Keyed to said main shaft 1'? is a sprocket wheel 18 operably connected bymeans of a sprocket chain 19 with a sprocket wheel 20, which latter is operated by said traction wheel 3. While the main shaft is illustrated as. being oper- '-ated from-the vehicle traction wheel, it may be operated by an independent motor or engin'e carried on the "vehicle frame or from any other rotatable element to be found in plows of this type.

Loose upon the main'shaft are locking disks 29, 30, 31 and 32, the disk 29 being 35 arranged or located at a point on theshaft in line with the beam 14 of the plow frame 9, and the remaining lockin disks 30, 31

and 32 are similarly locatec relatively to their plow frames 10, 11 and 12. Keyed to go the main shaft 17 are ratchet wheels 33, one being provided for each locking disk, on

one side thereof, andeach locking disk is held between its ratchet wheel 33 and a. collar 34, the latter-also fixed to the main shaft Upon one side-0f each locking disk are journaled two lifting pulleys 36, which. upon rotation of the locking disks, as indicated by the arrows in Figs. 2, 3, 4 and 5,

engage the plow-frame raising and lowering chains 16, thereby raising the plow frames on one half revolution of the looking disks and lowering them upon the other half revolution of said disks; While the 16 are shown'apparently in contact with the shaft, but by referring to Fig. 6, it will be noted that the locking disks are each equipped with o huh portion 3? around whichfthc said or 16 pass to prevent abrasion of the main shaft 1? and displacement of the chain The mechanism for rotating the locking disks comprises two pawls 920 and. 41, a pair being pivotelly fnounteo". by pins and 43, upon each of locking disks One end 2, i" provided 'Wlil'l a collar-e l zzrliptecl to cheer one of the nofiches in ratchec wheels c3. ill-he roller encl of one pswlof each isk i connected by means 01" rod or link so with the opposite end of the ol'her pawl of l re pair so that the roller ends of both associated pawls will sci upon his ratchet Wheel 33 in the some inanneia Tlhe roller end or" she pawls are normally drawn into engagement with the ratchet wheel by means of e spring L6 attached to the roller end of pawl 40 and to she pivot pin of he com--v pleinencpawl ll. The locking disks provided with peripheral notches 4 8 49 at diametrically opposite points, and the tail ends 01' the pewls Oencl 4.1 are so relates? to said notches l8 and 4:9 respectively that when the roller ends or" the pan-ls are gagecl with the ratchet Wheel 33, said toil ends will "move outwardly to overlap said notches as will be apparent.

Pivotally mounted upon the forward end of the vehicle frame are afoot levers 51, 52 53, 5e operable independently. These levers may be operated sh'nultaneouslyhy means of main foot lever 55 pivoted moon she shail: portions 56 of the foot levers 51 and 54 and engaging all of said foot levers.

Each of the foot levers i1, 52, 53, 54 is the form of a bell-crenlgihe foot depressing portion being substantially/in a l1orizontal plane and the locking, portion extending upwardly to 21 point in horizontal elinement with the axis of the main shaft 17' Where it is'hent' at right angles and pro vicled with a roller 57, adapted to enter one or the other o'f the lockingclisli notches S eQ, doc to the releasing of pressure by. the foot and the action of she spring 58 attached to" each foot lever and to the bar 5 of she vehicle frame. Owing to the diagonal arrangement of the plow frames, the pulleys 36 are arranged at different relativepoincs on the locking disks, illustrated in Figs. 2, 3, 4, 5, and disgrsimnsicslly in Fig. '1' in order that the plows will. enter and leave the soil at different times successively so that the furrows Will begin we end at the some points.

The operation is as follows: Upon the plow vehicle being drown or propelled over the soil, a continuous rotary motion is impar/ed by sprocket chain 19 so the main shaft 1?, and to she wishes wheels 33 keyctl 'zlherehi. The locking clislrs 29, 31 and 32 being loose upon the resin chefs l? are helol posisions assumed vihen the plows messes against retailer. by means of *he roller oi she ioos, levers 51, 53 ezi'c'i engaging in one or #:he oiher of the locking disk notches, clue so the scion of 58 normally 'cl rewing sci-cl roller ends 57 of fool:

The mil encl of the pa. vi if is pressecl imvsrolly by the roller of the foot lever thereby holding she roller end 4:4 oi pawl e0 out of engagement wish the ratche, Wheel against the action of spring +16 Fowl 4.1 it Will be armies acts the some as pawl 40 due to the conneci;- link e5. in rhese positions, the various elements remain during the plowing operacionw When it is desired to discontinue the plowing, the operator depresses the loci; levers by pressure upon the roaster lever thereby Withdrawing the roller ends 5'? the notches permitting the, spring 48 i0 chew the roller ends l of the "perils t-i0-i l into locking; engagement Wliill the ratchet WllBQlS -33 thereby causingshe disks 29, 39, 31 and 32 to rotate wijsh the main shaft 17 in the direction indicel ed by the arrows. During the half rotation of "she locking islzs, the pulleys thereof will successively engage the chains 16., clrewing upon the same to successively raise the plows from engagement with the soil. Pressure is released upon she foot levers assoon as the disks begin te ror-ate and the rollers 5'? of said-foot levers remain in rolling contact Wii? 1 the oeriphery oi the said locking disks until notches 49 preseni themselves, at which time sprlngs 58 will cause szncl ioller ends 57 to fell into said notches .49, depressing the toil ends the pawl. 4:1 and raising the roller fiends 44lthereof from engagement with the ratchet Wheels 33; pawl 49 being similarly affected clue to link 45. Thus the locking'dislrs rivill once more he held stetionery until is is'again desired to lower the plows oto the-soil. During the lowering operationshe-Weight of the plows will cause the lccldngflislcs to run away from ratchet, Wheel and turn too fast, ancl to prevent this a pawl is provided on each of the locking disks for engagement with the adjacentratcher, Wheel.

The theory of operation of the plow rolls ing devices is more clearly illusiretecl in Elia-7 gram in Fig. 7. When the plows are. to he raised, the (iislcs 29, 30, 31 and 32, which are indicates by lever E are roteteol in the direction oi? file arrow, th .rehy mo ing sheir respective pairs of pulleys 36 from he positrons a, a; 5.; 5; 0, c; d, d; eml chains menace "to the positions. AQ- li' 'C DQ When the parts are in the positions indicated by the reference letters bearingexponents, the

plows are in their raised positions. Letter F indicates the points where theflchain 16 is attached to the vehicle frame, and letter G the pulleys over which the chains pass to the plows. In the diagram the measured or independently under manual control,'it'

will be understood that the invention as herein set forth is limited to a single plow ing unit and the devices for raising and 20 lowering it.

I do not herein claim the series of plowing units and the series of lifting devices so constructed and related as to automatically lift the plows in uniformly timed succession;

and I do not herein claim the devices which make it possible for the operator .to set all of the lifting devices into operation simultaneously or to set one or more of them into operation independently of the others. These features above disclaimed are presented in my copending application, Serial No. 876,671, filed December 11, 1 914, as a division of this application.
